The SAS-3 Archive

The SAS-3 archive contains only raw
data files in their native format .
The data are organized per orbit and there are eight files for each
orbit containing scientific data and part of the HK information.
The file prefix indicates the data content
(QAK for tube collimator experiment, SLA slat collimator experiment,
LED low energy experiment, RMC modulation collimator, QAJ anti-coincident
ORB orbita data, SCO sco monitor, ZSN star sensor).
HEASARC does not have any suitable documentation on the specific data content
and structure. There is software available that read the raw data however
is all Sun-specific and it is not ported on current Sun operating system.
HEASARC has no plans to convert this data set in FITS.
The current version of the data and software are available
in the
HEASARC FTP area .
